(57) A visual display system for use in converting calligraphic symbology information
into raster scanned symbology. The system simultaneously generates and displays calligraphic
and raster matrix imagery utilizing the same set of software instructions. The imagery
is displayed upon a single, hybrid calligra- phic/raster matrix display (10) or separate
raster matrix and calligraphic displays. A programmable calligraphic symbology generator
(20) utilizes digital stroking techniques that successively generates addressing for
a matrix arrayed memory and determines the attributes of both the raster matrix generated
and calligraphic generated symbology. The information is stored in a single or a plurality
of matrix arrayed memories according to desired symbol attributes and system performance,
and is passed via a raster image buffer (30) to the matrix display (10).
